I think this CVE is invalid since it was then reverted by
upstream commit 647dd2c3f0e1 ("erofs: Revert "erofs: fix kvcalloc()
misuse with __GFP_NOFAIL"")
since it's not the correct way to fix this.
The original issue was fixed by
commit e9c3cda4d86e ("mm, vmalloc: fix high order __GFP_NOFAIL
allocations") instead.
